I posted this to the comp.lang.tcl newsgroup, but it might relate to a
possible bug in the Mingw32 cross-build environment under CentOS 6 (or EPEL).

I am trying to cross-build Tcl (8.5.8) and I have encounted two problems:
One I easily hacked the sources (wrapped the offending lines with #ifdefs):
./../generic/tclPosixStr.c:347:5: error: duplicate case value
case EPFNOSUPPORT: return "EPFNOSUPPORT";
^
./../generic/tclPosixStr.c:290:5: error: previously used here
case ENOPROTOOPT: return "ENOPROTOOPT";
^
./../generic/tclPosixStr.c: In function 'Tcl_ErrnoMsg':
./../generic/tclPosixStr.c:795:5: error: duplicate case value
case EPFNOSUPPORT: return "protocol family not supported";
^
./../generic/tclPosixStr.c:738:5: error: previously used here
case ENOPROTOOPT: return "bad protocol option";
^
The other I am not sure how to fix:
i686-w64-mingw32-gcc -c -O2 -fomit-frame-pointer -Wall -I"../../generic" -DTCL_TOMMATH -DMP_PREC=4 -I"../../libtommath" -I".." -DPACKAGE_NAME=\"\" -DPACKAGE_TARNAME=\"\" -DPACKAGE_VERSION=\"\" -DPACKAGE_STRING=\"\" -DPACKAGE_BUGREPORT=\"\" -DSTDC_HEADERS=1 -DHAVE_NO_SEH=1 -DHAVE_NO_LPFN_DECLS=1 -DHAVE_ALLOCA_GCC_INLINE=1 -DHAVE_CAST_TO_UNION=1 -DTCL_CFGVAL_ENCODING=\"cp1252\" -DHAVE_SYS_TYPES_H=1 -DHAVE_SYS_STAT_H=1 -DHAVE_STDLIB_H=1 -DHAVE_STRING_H=1 -DHAVE_MEMORY_H=1 -DHAVE_STRINGS_H=1 -DHAVE_INTTYPES_H=1 -DHAVE_STDINT_H=1 -DHAVE_UNISTD_H=1 -DTCL_CFG_OPTIMIZED=1 -DTCL_CFG_DEBUG=1 -DBUILD_tcl "../tclWin32Dll.c" -o tclWin32Dll.o
./tclWin32Dll.c:65:3: error: conflicting types for 'EXCEPTION_REGISTRATION'
} EXCEPTION_REGISTRATION;

^
Is there a solution possible? This looks like internal inconsistency with the
header files that are part of the build toolchain.
